engine crack repair

[Peter Nieuwlandt]

Hi

Does anyone know or remember a product wich may be called "Ironside" wich was used to fill up cracks in engine blocks.
It was used to repair the very early 1900's engines!Only the low compression engines of course.
It was some granulate substance wich was poured into the water jacket and heated up.
Any info on this or any other product to repair cracked blocks is appreciated

Peter, It depends upon where the crack is located. I had some-year of an ARMY tank engine in my '38 la Salle, which had a crack in the IN-TAKE VALVE SEAT and into the cylinder. I had the engine torn-down and I used a NICKEL-ALLOY welding rod  with the flux removed. Drilled
and TAP the crack,treaded welding rod, dipped it in some "BARRES STOP LEAK" screwed rod into block, grind valve seat if neccessary.  Have never heard of the compound you spoke of ,but, it should work OK. The welding rod methold was taught by John-Deere - to include diesel engines.

G'day Peter,

I think that the product you are referring to is "Irontite" or some similar spelling.

It works very much like Bar's Leaks (www.barsproducts.com), which I have great faith in, and Silverseal (my container is too old for an internet address) which has minute particles of a metallic substance that fills the gaps when exposed to air.

These products state that they:
Bar's Leaks..."Permanently seals leaks in plastic, aluminum (aluminium), and metal radiators, heater cores, blocks, heads, gaskets, and freeze plugs"
Silverseal ..."Repairs cracked motor block and leaks in radiators of auto, truck and tractors"

Forget about all the store bought products for sealing cracks. I dont know if you remember evaporated milk or pet milk, this  I have used and works excellent. First drain all antifreeze flush engine if neccesary, fill with water, run engine until it gets warm leaving radiator cap off. Once it gets warm pour can of pet milk in radiator. This stays a liquid while in the water but once it hits the crack in the block it cooks like an egg, hardening like a rock. But the good thing about it is, it doesn't clog your radiator like many other products. good luck.

Guys,

I don't want to rain on your parade, but it's all just a band aid.  Eventually, whatever slop you pour into the cooling system will either clog what you don't want clogged, or will start leaking again, possibly allowing coolant to mix with your oil.

I have owned and fixed many HT4100 powered cars, and my opinion is that the GM additives as a preventive measure are a good thing, but the Bar's Leak Block sealer, and the other heavy duty block and head sealers, well that stuff is made for the Pep Boys crowd, and the used car hucksters.  If you have a collector car worth keeping, it's a car worth fixing.  I wouldn't like driving something that i constantly have to worry about, and keep checking for leaks, but that's just my opinion.

Here are 2 photos.  A head gasket failure on an 85 "rebuilt" HT4100, and the completely rebuilt engine that I installed with all the updates, and it still runs like new, no leaks of any kind.

My band-aid fix lasted for at least 5 years and 50,000 miles with no reoccuring problems, the car was sold and still ran for quite some time. That's a pretty good band-aid I'd say. A can of pet milk costs about $1.50.
